Anatomy of a metal detector
The metal detector is modern technology features lightweight, easy to use and contains the following components
Installed or Kufr daifth maintains fixed unit during the stirring gold trip
Control box-contains circuits and controls, and the speaker and batteries and microprocessor
Shaft or the arm connecting the control box and the coil and is adjustable in height is right for you, you can specify by length comfortable walking without bending back it in a comfortable level for your height
Search coil-the bottom which is close to the ground actually senses metal; aka “search,” “loop” or “antenna”
Most systems also socket to connect the headphones, some control box at the bottom of the shaft, and a small display above.
